Speakman a-tmv Thermostatic Mixing Valve 3/8 Inch

Product Description

The SPEAKMAN a-tmv is a thermostatic mixing valve designed for under-counter installation in plumbing systems. It blends hot and cold water supplies to deliver a controlled, tempered water output, protecting end users from scalding and maintaining consistent outlet temperatures. The valve connects via 3/8 inch compression male threaded inlets and outlets, making it compatible with standard under-sink supply line configurations. A minimum flow rate of 0.35 GPM is required for proper thermostatic operation. This valve is typically installed by licensed plumbers in residential and light commercial applications where point-of-use temperature control is required.

The a-tmv is suited for under-counter installations where space is limited and precise water temperature control is critical. Common applications include accessible or ADA-compliant lavatory setups, healthcare hand-washing stations, and residential bathroom or kitchen sink supply lines. The 3/8 inch compression male threaded connections allow for straightforward integration with standard flexible supply lines without additional adapters in most installations.
